JOSEPH a. HAGGEETY, or rHiLADELrniA, PENNSYLVANIA "WHEEL-MOUNTING ron MOTORCYCLES.

To all whom it may concern."

Be it known that I, JOSEPH A. Hessnnrx, a citizen of the United States, residingat Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful, Improvements in Wheel-Mountings for Motorcycles, of which the following is aspecification.

The difficulty of removal and replace V ment of the driving wheels of'motorcyoles is well known. 7 This difficulty of removal and replacement of the, driving wheels is due principally to the inclusion of the necessary brake construction and surrounding parts of the frame and wheel mounting 7 whichhave heretofore been complicated, re-

quiring the removal of numerous parts he- .fore the driving wheel could be removed or the parts of the wheel-bearing adjusted. One object of my' present invention is to provide a construction which will permit the driving wheel of amotor cycle to be justed.

easily and quickly removed and replaced.

Another object is to so make my improved construction that it will permit the parts of the bearing to be easily and quicklyv ad- Astillfurtherobject is to make the parts of my invention of a simple, strong and durable construction whichcan be practically embodied in a motorcycle.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Y 1 I I Figure 1 is a sectional elevation taken centrally through the rear driving wheel of the motorcycle and the surrounding parts of the brake band, frame, and bearing,

Fig. 2 is a transverse section taken on theline 2-2 of Fig. 1, l

Fig. 3 is a view. showing certain of the parts illustrated in Fig- 1 and drawn on an enlarged scale, .I

Figs. 4, 5,6, 7 8 and 9 are perspective 7 views illustrat ng certain of the features of 'my invention; Fig. 8 being shown in cen .tral longitudinal section.

Y Referring to the drawings, 10' represents I parts of the frame of a motorcycle which are located on opposite sides of the. driving wheel 11; the part 10 on one side of the driving wheelbeing provided with one element, such as shown at 12,0f a brake made 7 in the' form of brake drum in which fits Specification of LettersPatent.

the brake band" 13; said brake band also gular in cross section and the axle is made angular in cross section so as'to be free to be slid longitudinally therein and rotate in conjunction with the driving wheel. The

disk 14 also has an angular hole through v which the axle 18 freely extends and an actuating wheel, illustrated in the form of a driving sprocket. 19 adjacent the opposite side of the hub has an angular hole 20 through which said axle 18 extends.

Bearing sleeves 21 and 22 which are preferably similarly constructed are secured respectively .to the disk 14 and sprocket 19; said sleeves having central holes whichare angular in cross section and through which the angular axle 18 freely extends.v The sleeve 22 has an externally screw threaded portion. 23 upon which is screwed a collar 24; saidcollar having an inwardly projecting tapered or frusto-conical portion 25.

The sleeve 22 has a frusto-conical portion 26 opposed to the portion 25 of the collar and a ring 27 which fits'within the right hand frame portion 10' has an inwardly tapering circular rib 28. A series of ball bearings 29 are interposed between the frusto-conical portion 26 and one side of the rib 28 and a second series .of ball bearings 30 is interposed betweenthe frustoconical portion 25 of the collar 24 and the adjacent side of therib 28 as clearly shown in Fig. 1.

An adjusting ring 31 is interposed between the collar 24 and the head 32 of the axle 18;

this adjusting ring being preferably screwed onto the portion 23 of the sleeve 22. The adjusting ring31 is preferably of such diameter as to fit within the cavity 3 3 of the- I ring 27 in which the collar 24 is located and is provided with a number of screw threaded holes 34 in which small screws 35 fit. The inner ends of the screws 35 are adapted to abut the outerface of the collar 24 and the head 32 of the axle 18 is of such diameter as to cover the screw threaded holes 34. The

outer face of the adjusting ring 31 projects c on the sleeve 21 and a ring 37 is fitted with in the frame portion and provides a clot,

beyond the outer face of the ring 27 so thatthe axle head 32 contacts with the adjusting ring 31 and is free of the ring 27 7 At the opposite side ofzthe driving wheel a collar 36 similar to the collar 24 is screwed sure for the sleeve 21 and collar 36. This ring 37 has a circular inwardly tapering rib 38 and two series of. ball bearings 39 and 49 are interposed between the frusto-conical portions 41 and '42 of the collar 36, sleeve 21 and rib 38. An adjusting ring 43 is preferably screwed on the outer end of the sleeve r 21 and fits within the cavity 44 of the ring 37 so that a portion of the adjusting ring 43 projects beyond the outer surface of the ring 37. The adjusting ring 43 is constructed similarly to the adjusting ring 31 above noted and includes a number of screw threaded holes 45 in which are threaded screws 46 adapted to abut the outer surface of the collar 36. The end of the axle 18 opposite the head 32 is screw threaded as shown at 47 and a cap nut 48 is screwed on the end 47 and abuts the outer surface of the adjustingring 43. A cotter pin 49 extends through the cap nut 48 and a hole 50 in the end 47 of the axle 18.

With the above construction, if it is desiredto remove the driving wheel 11, it is merely necessary to withdraw the cotter pin 49 and take off the cap nut 48. The entire axle 18 can be withdrawn by pulling outwardly on the head 32 and the driving wheel 11 will be freed and can be removed; the sprocket wheel, brake and bearingsremaining connected to the frame. If it is desired to take up or compensate for wear in the bearings, it is merely necessary to turn the collars 24 and 36 and then in order to keep the nut 48 and head 32 of the axle 18prop- I erly spaced the screws 35 and 46 can be turned inwardly so as to keep in abutment with their respective collars so that even after the adjustment of the bearings is made the outer surfaces of the adjusting rings 31 and 43 will remain the same distance apart as before the adjustment was made. V i

The parts can be readily disassembled and put together and no complicated mechanism is present. Furthermore with my improved construction it is not necessary, when-it is desired to remove and replace the wheel, to disturb the adjustment of the bearings unless aspreviously stated it is desired to adjust the bearings'to' compensate for wear.

VVhile' I have described .my' invention as taking a particular form, it will be understood that thevarious parts of'my inven; tion may be changed without departing from the spirit thereof, "and hence'I do not limit myself to the precise construction set forth, but consider that Iam at liberty to make such changes and alterations as fairly said axle having ahead located outside of come within the scope of the appended claims.
